            This option enables to convert SQLite database to BDB SQL database format. See <a class="xref" href="build_android_intro.html#build_android_migrate" title="Migrating from SQLite to Berkeley DB">Migrating from SQLite to Berkeley DB</a>

            <p>
            This flag is enabled by default and keeps all the region files in 
            memory instead of the disk. 
            This flag also implements database-level locking.

            SQLITE_DEFAULT_CACHE_SIZE
        </p>
            <p>
           SQLite provides an in-memory cache which you size according to the maximum number of
			database pages that you want to hold in memory at any given time.
			See <a class="xref" href="build_unix_sql.html#config_sql" title="Changing Compile Options">Changing Compile Options</a>.
        </p>
          </li>
          <li>

            SQLITE_DEFAULT_JOURNAL_SIZE_LIMIT
        </p>
            <p>
           For SQLite, this pragma identifies the maximum size that the journal file is allowed
			to be. Berkeley DB does not have a journal file, but it writes and uses log files. A new log file is
			created when the current log file has reached the defined maximum size.
			This flag defines this maximum size for a log file. Default value is 10 MB for Berkeley DB SQL interface.
        </p>
          </li>
        </ul>
      </div>
      <p>
Hard-coded numbers in the build can be adjusted using the following SQLite PRAGMA commands: </p>
      <div class="itemizedlist">
        <ul type="disc">
          <li>PRAGMA cache_size</li>
          <li>PRAGMA journal_size_limit</li>
        </ul>
      </div>
      <p>
You can configure most aspects of your Berkeley DB environment by using the <a href="../api_reference/C/configuration_reference.html" class="olink">DB_CONFIG</a> file.
